Monoethanolamine, raug cai 2-aminoethanol, yog kua nplaum, alkaline kua nrog ib qho tsis kaj siab, zoo li ammonia tsw.
2-aminoethanol ntau lawm txoj kev
Ethylene oxide thiab ammonia reacts nyob rau hauv ib tug aqueous tov los tsim ib tug sib tov ntawm monoethanolamine, diethanolamine, thiab triethanolamine. MEA cov txheej txheem ntau lawm yog exothermic heev, nrog rau qhov kub thiab txias mus txog qhov muaj peev xwm txaus ntshai. Yog li, kev ntsuas kev nyab xeeb nruj thiab cov cuab yeej tshwj xeeb yog qhov tseem ceeb rau kev nyab xeeb thiab muaj txiaj ntsig monoethanolamine ntau lawm.
Vim li cas 2-aminoethanol tseem ceeb?
2-aminoethanol / Monoethanolamine (MEA)yog ib qho tseem ceeb organic compound nrog cov tshuaj formula C₂H₇NO. Nyob rau hauv chav tsev kub, nws zoo nkaus li tsis muaj xim, kua nplaum nrog ammonia -zoo li tsw thiab muaj zog alkalinity. Raws li kev siv tshuaj lom neeg ntau, MEA pom cov ntawv siv dav hauv kev lag luam, tshuaj, kev ua liaj ua teb, thiab kev saib xyuas tus kheej.
